fix: resolve ESLint errors for unused imports and no-explicit-any

Remove unused SchemaType imports from builder.ts, navigator.ts, and
generator.ts. Remove unused buildOperation import from generator.ts.
Replace `any` type annotations with proper types to satisfy
@typescript-eslint/no-explicit-any rule.
